Lby pragma/ not extend. forward to thel front wall 4 of the box, ybut leaves from 21,- to 3 inches more or less open space, as seen at 15, extending all along the l'ront wall. The side walls near the front wall and abovev the hoverer board are provided with openings 16. Tl'irough these ventilating openings 16 of about 11% inch diameter, in the side walls the air troni the outside can. enter the space under the cover 14 near the iront wall and above the hoverer at both ends ot' said open space between the hoverer and the i'ront wah and pass down through the same to the bottom of the box. When the air under the hoverer board is warmed, as it will be by occupancy for a short while by a brood otchicks, a circulation will be started. by the tendency of warmer air to rise up against the imperlorato hovorer board which forms a tight closure ol" the doublewall portion ot the box at all pointsexcept the front, serves to prevent the warm air from rising too high above the screen floor and directs the movement of upper air stratum or warmest part toward the front. The movement of the upper stratum ot air under the hoverer board toward the liront of the box is to the required extent checked by the depending slitted strips but it is permitted to pass out slowly into said open space at 15 and thence up and out through said openings 16 while the outer cold air entering the box through said opening 16 and descending through said open space at l'is allowed to pass slowly lroni theliront toward the rear of the box in the open space below the dependent slitted strips and under the screen' V1U ultimately to rise and take the place oi' the foul air which has passed ott .from i1n.

mcdiately below the hoverer board through the slits in the pendent strips. Y

The air can. circulate under the pendent slitted cloth strips and also under the screen floor so that it some of the chicks in the br'ood are knocked down and trampled on in the huddle they can still breathe from the air below the screen and so will not smother.

The dimensions oi' lrooder box and other paris given are designed and adapted to accommodate from to 100 chicks three weeks old, at first filling the hoverer comfortably l'ull and afterwards reducing the number they get larger.

Acccnding to the usual practice in raising incubator chicks theyy are kept in lampheatedbrooders until three weeks old and then turned to roost without other means than the common. coop to protect them from the cold. With such keeping they huddle in the coop too closely and come are sutiocated or hurt by being trinupled on, and all suiler Ymore or less from cold.

in consequence of the cold they do notv thrive well and many get'sick and die before they are six weeks old.

I have thoroughly tried my iin'prov'ed broeder for two seasons and found 1t wellk adapted to the work for which it is intended. Harbored by it the chicks get very hardy and grow and thrive well, in fact a great deal better than they do in lamp-heated broeders. l'articularly, it is proved that the hoverer constructed as I .have shown secures thesafe huddling of the chicks 'in the coop so as to prevent the1rinJurmv` one another and so as to combine and apply the Warmth of their bodies for suliiciently warming the inclosure tor their protection trom cold. it 1s also proved that the chicks get all the ventilation Y they require from the iront si'de only of the .coo p provided with such hoverer and having the elevated screen floor under which the air can pass at the front side. rrihe cover being lifted oli, the hoverer and the scrcencan be taken out for cleaning the box whenever desired. l

What I claim:

1.?. A chicken broeder comprising a box like structure provided with an entrance opening, Ventilating openings, and a detach-l able cover, a detachable screeniloor sup-' ported above the bottom of the box, a detachable iinpertorate plate shorter at the.

front side than the box bottoni and provided with a cluster ot regularlyspaeed harrow cloth parts pendent therefrom and tac-4 ing toward the front of the box, and means for supporting said plate within the box with said pendent parts clear oi", the screeny floor and clear of the front wall of thebox 2. A chicken broeder comV risinga 'boxlike structure provided with a iorizontal partition shorter 'at the front side than the box bottom', an entrance opening in the front side and ventilating openings above the par titien in proximity to the front side, in com bination with a cluster ot regularlyfspaced cloth.1 strips suspended from the under side .of the partition and extending downwardlynearly to the box bottom, said stri s being extended arallel with the front Wal of the box and`s itted from the bottomupwardly to the partition, vthe arrangement being such as to provide air spacewithi'n the box extending horizontally under said cluster and vertically between it and the frontwall ofi the box to the space above the partition.
